As a terrestrial plant, this orchid plays a role in soil stabilization and nutrient cycling.
Conclusion
Schizoglossum excisum Schltr. is a breathtaking orchid native to Papua New Guinea. Its unique appearance and relative rarity have made it a desirable plant for collectors and horticulturists alike. Its importance in the ecosystem in which it is found also make it an important species to protect and conserve.
Light Requirements
Schizoglossum excisum Schltr. prefers bright, but indirect sunlight. It can also tolerate partial shade. Too much direct sunlight can damage the plant's leaves.
Temperature Requirements
The ideal temperature range for Schizoglossum excisum Schltr. is between 18-25°C (64-77°F). The plant can tolerate temperature variations but is not well-suited to extreme temperatures.
Soil Requirements
Schizoglossum excisum Schltr. requires well-draining soil that is rich in organic matter. It prefers slightly acidic to neutral soil with a pH range of 5.5-7.0. The soil should be moist but not waterlogged, allowing for proper drainage. The addition of perlite or sand can improve drainage.
Cultivation
Schizoglossum excisum Schltr. is a terrestrial orchid that thrives in tropical regions. It requires warm temperatures and high humidity levels to grow adequately. The plant can grow up to 30cm tall and produces spikes that bear small white flowers. It is important to note that this plant is a protected and endangered species; thus, cultivators should obtain it from reputable sources.
Watering Needs
Watering of Schizoglossum excisum Schltr. should be done with caution. The plant cannot tolerate dry soil; it requires a consistently moist, well-draining substrate. The ideal potting mix should contain a mix of sphagnum moss, fine bark, and perlite. Water the plant at least once a week in the summer but reduce this frequency during colder seasons.
Fertilization
Fertilizing Schizoglossum excisum Schltr. is necessary to enhance growth and blooming. It is recommended to use a balanced, water-soluble fertilizer every two weeks during the growing seasons. Dilute the solution according to the manufacturer's instructions before application.
Pruning
Pruning Schizoglossum excisum Schltr. is not necessary. However, it is advisable to remove its spent or withered flowers. This practice enhances the plant's appearance and encourages the development of new blooms.
Propagation of Schizoglossum excisum Schltr.
Schizoglossum excisum Schltr. is a terrestrial orchid species native to the tropical forests of Southeast Asia. It is commonly known as the "Star-Shaped Lipped Schizoglossum." The plant can be propagated through two methods: division of clumps and seed sowing.
Division of Clumps
Division of clumps is the most common method of propagating Schizoglossum excisum Schltr. This method involves separating the plant from the mother plant that has formed a clump. Dividing the clumps can be done during the growing season when the new shoots have fully developed and are ready for separation.
To divide the clumps, first remove the plant from its pot and gently separate the clumps with a sharp and sterilized knife. Each divided clump should have at least one new growth and a few roots. After dividing the clumps, repot each section into separate pots containing a well-draining potting mix. Water thoroughly and place the new plants in a shaded area, gradually increasing the light as the plant becomes established.
Seed Sowing
Seed sowing is another method for propagating Schizoglossum excisum Schltr. This method requires growing the plant from seeds. Collect the seeds when the seed pods turn brown and start to split open on their own. The seeds require proper treatment before sowing since Schizoglossum excisum Schltr. seeds have a low germination rate.
To treat the seeds, soak them in a solution of water and fungicide for 24 hours before spreading them on a moist paper towel in a warm and humid place. After three weeks, the seeds will start to germinate. Transfer the germinated seeds to a pot filled with a well-draining, sterile potting mix. Keep the soil slightly moist and place the pot in a shaded area. Gradually increase the light as the plant becomes established.
Disease Management
One of the most common diseases that affect Schizoglossum excisum Schltr. is fungal leaf spot. This disease is characterized by circular or irregular brown spots on the leaves. To prevent fungal leaf spots, it is recommended to avoid watering the plant from above, and instead water the soil directly. If the disease is already present, it is possible to manage it by removing the affected leaves and treating the plant with a fungicide.
Another disease that can affect Schizoglossum excisum Schltr. is bacterial wilt. This disease is caused by a bacterium that can enter the plant through wounds or soil. Bacterial wilt causes wilting of the leaves and stems, and eventually leads to the death of the plant. To manage bacterial wilt, it is important to remove and destroy all infected plants immediately. It is also recommended to avoid planting susceptible species in the same soil.
Pest Management
One of the most common pests that can affect Schizoglossum excisum Schltr. is mealybugs. Mealybugs are small insects that can be found on the leaves and stems of the plant. They are identified by their white, cotton-like appearance. Mealybugs can be managed by removing them manually with a cotton swab or by treating the plant with a natural or chemical insecticide.
Another pest that can affect Schizoglossum excisum Schltr. is thrips. Thrips are small, slender insects that can cause damage to the leaves and flowers of the plant. They are identified by their long, narrow wings. To manage thrips, it is recommended to remove all affected plant parts and treat the plant with a natural or chemical insecticide. It is also recommended to keep the plant in optimal conditions to prevent infestations.
